JDK-8189762 - [TESTBUG] Create tests for JDK-8146115 container awareness and resource configuration
Description
When running on machine with 2 CPUs, the test test/hotspot/jtreg/runtime/containers/docker$ enw TestCPUAwareness.java fails. 
The test should check for number of CPUs available on a test host/node and skip test configurations that are not applicable for given number of CPUs.

Addressed feedback from Bob and David: http://cr.openjdk.java.net/~mseledtsov/8191943.02/

After discussions with Bob I took a different approach. Rather then limiting test case execution for cases exceeding the available CPUs the change now updates expected Active Process Count value to not exceed the number of available CPUs. This closed reflects the VM behavior. Here is the updated webrev: http://cr.openjdk.java.net/~mseledtsov/8191943.01/
